Randolph ABSTRACT: A holder or dispenser attached along the ridge of a roof and containing a chemical capable of being gradually dissolved by moisture so as to bleed from the holder and flow down the roof surface for cleaning the roof of stains and discolorations, for coloring the roof or for restoring the original color thereof.

QPATENTEDIIAR 2m as [he l-(le ATTORNEY THEODORE M.WILLIAMS ROOF TREATING DEVICE It is a primary object of the present invention to provide a holder capable of being attached along the ridge of a roof and containing a chemical which is gradually dissolved by moisture, so that the chemical will bleed from the holder and flow down the roof surface for cleaning the roof of stains and other discolorations resulting from various causes including mold and mildew, and for preventing the reoccurrence of such discoloration.

Another object of the invention is to provide a holder capable of containing slowly dissolving chemicals for coloring or restoring the original color of a faded roof.

Various other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawing illustrating presently preferred embodiments thereof, and wherein:

FIG. 9 is a cross-sectional view thereof, taken substantially along a plane as indicated by the line 9-9 of FIG. 8, and

FIG. 10 is a cross-sectional view'of still another embodiment of the treating device.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring more specifically to the drawing, one embodiment of the roof treating device, designated generally 12, is illustrated in FIGS. I to 4 and comprises two corresponding tubular members 13 each of which is filled with a suitable chemical 14, and each of which is provided with a multiplicity of apertures 15. The members 13 are illustrated in FIG. 3 as being of rectangular cross section with top and bottom walls substantially wider than the sidewalls thereof; however, said members 13 could be of various other cross-sectional shapes. The apertures 15 are formed in said top and bottom walls and sidewalls. The members 13 are preferably provided with imperforate or solid end walls 16, as indicated in FIG. 1.

The two members 13, constituting the chemical holder or dispenser, are connected to one another in spaced-apart substantially parallel relation by a web member 17 having side edge portions which are suitably secured to the members 13 in any conventional manner by an adhesive or stitching, not shown. The web 17 is formed of a flexible and porous material and extends from end-to-end of the members 13. The exteriors of the bottom surfaces of the members 13 are provided with transversely extending stripes of a coating material 18, as best seen in FIG. 4.

The dispenser 12 is of a length to extend from end-to-end of the'ridge of a roof 19 with the web 17 engaging across the roof ridge, as seen in FIG. 2, and the members 13 resting one on each of the sloping sides of the roof adjacent toe ridge thereof and secured thereto by the adhesive coatings 18. Additionally, the web 17 may be provided with spaced openings 20 for receiving nails 21 which can be driven into the ridge of the roof for additionally securing the holder 12 thereon, especially in areas subject to strong winds.

The members 13 may be formed of various materials including certain metals and plastics and may be either rigid or flexi-- ble. The chemicals 14 may constitute various metal oxides or bleaching materials or a combination thereof which will dissolve gradually when exposed to moisture, so that rain water or dew will cause the chemicals to bleed gradually through the perforations l5 and flow down the sloping sides of the roof for cleaning the roof of discolorations resulting from various causes such as mold and mildew, which is especially common during prolonged periods of damp weather, and for also restoring the original color of a faded roof or for staining the roof a desired color.

FIG. 5 illustrated a slightly different embodiment of the treating device, designated generally 22, for use on a single sloping roof 23, and comprising a single tubular member 13', corresponding to one of the members 13, to one sidewall of which is connected a flexible tape 24 which may be secured by nails 25 to a vertical wall portion 26 of the building, adjacent the ridge of the roof, for cooperating with the adhesive coatings 18 to retain the member 13 in place on the roof 23 adjacent its upper edge or ridge. The treating device 22 will function in the same manner as heretofore described in connection with each of the tubular members 13.

FIGS. 6 and 7 illustrate another embodiment of the roof treating device, designated generally 2.7, comprising two coarse woven fabric strips or pads 28, each of which is impregnated with the chemical or chemicals, and which are connected to one another in spacedapart substantially parallel relation to one another by a web 29, corresponding to the web 17. The underside of the strips or pads 28 are provided with adhesive coatings 30 corresponding to the coatings 18. The treating device 27 is applied to a double sloping roof, such as the roof 19, in the same manner as the treating device 12 and functions in the same manner to accomplish the same results.

FIGS. 8 and 9 illustrate a further embodiment of the invention comprising a roof treating device 31 comprising two strips of coarse mesh wire fabric 32, each of which is impregnated with the chemical or chemicals, and which are connected together in spaced-apart relation to one another along adjacent edges thereof by a web 33, corresponding to web I7. Strips of adhesive coatings 34, corresponding to the coatings 18, are applied to the undersides of the mesh wire fabric strips 32. The treating device 31 is applied and functions in the same manner as the roof treating device 12.

FIG. 10 illustrates a final embodiment of the roof treating device, generally designated 35, comprising two elongated relatively wide metal'strips 36 which are connected together along adjacent longitudinal edges thereof by a web 37, corresponding to the web 17. The strips 36 are shown encased in a coating 38 of the roof treating chemical or chemicals. Adhesive coatings 39, corresponding to the coatings 18 are provided on the undersides of exposed portions of the strips 36 or on portions of the undersides of the coatings 38. In lieu of the chemical coatings 38, the strips 36 could be impregnated with the chemical. The treating device 35 is applied and functions in the same manner as the treating device 12.

It will be readily apparent that the treating devices 27, 31 and 35 could be made as single units for use on a single sloping roof in the same manner as the treating device 22. It will also be apparent that the treating devices 27, 31 and 35 could be made flexible to be sold in rolls to be cutoff to proper lengths corresponding to lengths of roofs to which said treating devices are to be applied.

Various other modifications and changes are contemplated and may be resorted to, without departing from the function of the scope of the invention.
